The esophagus runs through the diaphragm to the stomach. It functions to carry food from the mouth to the stomach. The esophagus passes through the diaphragm just before it meets the stomach, through an opening called the esophageal hiatus.
When the opening (hiatus) in the muscle between the abdomen and chest (diaphragm) is too large, some of the stomach can slip up into the chest cavity. This can cause heartburn (gastro-esophageal reflux; GER) as gastric acid backflows from the stomach into the esophagus. Hiatal hernia repair is surgery to repair a bulging of stomach tissue through the muscle between the abdomen and chest (diaphragm) into the chest (hiatal hernia).
Hiatal hernia repair may be recommended when the patient has:
While the patient is deep asleep and pain-free (general anesthesia), an incision is made in the abdomen.
The stomach and lower esophagus are placed back into the abdominal cavity. The opening in the diaphragm (hiatus) is tightened and the stomach is stitched in position to prevent reflux. The upper part of the stomach (fundus) may be wrapped around the esophagus (fundoplication) to reduce reflux.
Patients may need to spend 3 to 10 days in the hospital after surgery. A tube will be placed into the stomach through the nose and throat (nasogastric tube) during surgery and may remain for a few days. Small, frequent feedings are recommended.
